Fountek

Fountek is an innovative far east manufacturer of ribbon tweeters. The product quality (even mechanical details like the neat rear damping coat of the front plate), the powerful Neodym magnets, the high efficiency and the flat frequency response convinced us. Therefore, selected pairs of ribbon tweeters with metal front plate (Fountek also supplies common types with plastic front plate) are available under the name Audaphon/Fountek.

The following ribbon tweeters are so-called real ribbons, with built-in transformer, since ribbons of around 0.02 Ohm have a too low resistance to be wired up directly.

There are two different materials for ribbons: 0.009 mm aluminium foil, like the JP ribbons These ribbons show an incredible airiness; they need, however, to be protected carefully against low frequencies, by means of 18 dB crossover and should never be connected directly (without capacitor) to a measuring device.

The next type of ribbon is the Neo range with a stronger ribbon that is roughly 50% heavier and has with a 0.020 mm gauge double the thickness. These could be used in conjunction with 12 dB crossovers.

Particularly impressive is the Neo 5i ribbon, equipped with 4 high power Neodym magnets, totalling a weight of 2.7 kg.

The cabinet volume calculations are executed considering an external resistance of 0.3 Ohm. We are using, if no other data is known or available, the information supplied by the manufacturer.

Please note: the frequency response doesn't say much about the cut-off frequency inside the cabinet! Therefore, we mostly give you 2 examples with dimensioning considerations and an indication, how low the loudspeaker will reproduce.
